Step 1:I'll solve this step-by-step following the specified LaTeX and formatting guidelines:
Step 2:: Determine the Atomic Number of Magnesium
- For Magnesium (Mg), the atomic number is $$12
- The atomic number of an element represents the number of protons in its nucleus - In a neutral atom, the number of electrons equals the number of protons
Step 3:: Electron Configuration
- Total number of electrons: $$2 + 2 + 6 + 2 = 12
- Magnesium's electron configuration follows the standard atomic structure
Step 4:: Verify the Number of Electrons
- Counting the electrons confirms that Magnesium has $$12$$ electrons
Final Answer
Explanation: In a neutral Magnesium atom, the number of electrons is equal to its atomic number, which is 12. This matches option A in the given choices.
